Kutheni le nto iinjini eziqhelekileyo zingasetyenziswa njengeenjini eziguquguqukayo?

Ngokwesiqheloinjini yombanes zihlala ziyilelwe ukuphindaphindwa rhoqo kunye nosetyenziso lwevoltheji rhoqo, kodwa zijongana nemida ebalulekileyo xa kuziwa ekusebenzeni okuguquguqukayo. Ukungakwazi ukuziqhelanisa nokutshintsha ii-frequencies kunye ne-voltages sesona sizathu sibangela ukuba zingakwazi ukusetyenziswa ngokufanelekileyo njengeiimotor frequency frequencys.

Omnye wemingeni ephambili kunye neenjini eziqhelekileyo kuyilo lwazo, olulungiselelwe i-frequency ethile yokusebenza, ngokuqhelekileyo amandla aqhelekileyo angama-50 okanye ama-60 Hz. Xa i-drive frequency drive isetyenziselwa ukulawula isantya sezi motor, iimpawu ezisisiseko zemoto azihambelani neemfuno zokusebenza kwesantya esiguqukayo. I-drive frequency drive itshintsha i-frequency input kunye ne-voltage, enokubangela imiba yokusebenza ngeenjini eziqhelekileyo.

Ukongeza, iziphumo zeVFD injinikwimotor nako kunokuba yingozi. Ngokomzekelo, amandla okufakelwa kwee-motor windings anokwanela ukuphatha i-voltage spikes kunye nokwahluka okuvezwe yi-VFD. Oku kunokubangela ukuba isigqumathelo singaphumeleli kwangaphambi kwexesha, nto leyo ekhokelela ekulungiseni okuxabisa imali eninzi okanye ukutshintshwa.

Kwizantya eziphantsi, ukupholisa ngomnye umba obalulekileyo. Iinjini eziqhelekileyo zixhomekeke kumoya othile owenziwe kuyilo lwazo ukuze zikhuphe ubushushu ngokufanelekileyo. Xa usebenza ngesantya esisezantsi, umphumo wokupholisa uyancitshiswa, okhokelela ekugqithiseni kunye nomonakalo onokwenzeka. Oku kuyingxaki ngakumbi kwizicelo ezifuna ukusebenza ngesantya esisezantsi kangangexesha elongeziweyo, njengoko i-motor ayinakukwazi ukugcina ubushushu bokusebenza obukhuselekileyo.

Imida yoyilo engokwemvelo yeenjini eziqhelekileyo, ezidityaniswa neziphumo ezibi zee-inverters kwi-insulation kunye nokupholisa, zibenza bangafaneleki usetyenziso lwamaza ohlukeneyo. Ukulawulwa kwesantya esisebenzayo kunye nokusebenza okuthembekileyo, iimotor eziguquguqukayo eziguquguqukayo zibalulekile kuba ziyilelwe ngokuthe ngqo ukuhlangabezana neemfuno zokusebenza okuguquguqukayo.
